Two machanisms have been discussed to give rise to a SN Ia: 1. A single white dwarf collects matter e.g. from the outflow of an accompanying red giant. As...

I have always wondered why black holes exist. Nothing in nature exists without some purpose. Why do they function the way the do sucking up mass and matter? ...

In the end, I did make those "Tales of Cataloguing" (quasar positional fixes posted here in October 2011) into a paper, now accepted by PASA. It can be seen at...

In most studies arriving at the conclusion of galactic dark matter, the virial theorem is applied to compute the mass of the structure in question from the...

] Can anyone explain why the Universe is everywhere the same temperature. It seems to me that the expansion must be limited to the Voids, because the bound...

Contrary to what I believed, the article of ESO that I pointed out last week is by far not the only serious article that cast doubts in the very existence of...

Well, reading this blog at: http://www.scilogs.eu/en/blog/the-dark-matter-crisis/2012-03-31/question-c.iii-fundamental-theoretical-problems I stumbled upon...

In today's batch of new preprints is: http://arxiv.org/abs/1204.5187 by Boley, Payne and Ford. Submitted to ApJ. The paper discusses planet scattering and...

Various experiments over the years have verified that no information travels faster than light as appears to be the case in regards to recently negated...

One of the most interesting observations are what is called SNLS data This is a table of values of the magnitude of Super Novae versus z values. Using that...

How many light years away is the expansion of Space expected to start? Also, At that point, would that not mean space time is not "Flat" any more?

I would like to save some links from the ADS abstract search. However, the automatically generated link is too long. I've found that a rather obvious...

In the preprint of "The HARPS search ... XXXI. The M-dwarf sample" by Bonfils et al, http://arxiv.org/abs/1111.5019 ] , Figure 1 and comments in section 8...

Conventional wisdom suggests that, like planets round the Sun, stars follow approximately circular orbits which cross the spiral arms, and that the Sun...

Those following the exciting developments relating to the apparent discovery of trillions of unbound, planetary-mass "nomads", and the growing interest in the...

The annual Doppler effect is the variation in frequency and wavelength of light from a distant star that lies near the ecliptic, due to earth's varying motion...

The americans are going to make their base at the south pole of the Moon, at Schackleton crater. There is no sunlight at the bottom, so how much of the...
